In a recent interview with fashion and beauty site Into The Gloss, K-Stew dished on her makeup and hair tips -- and revealed something that we never saw coming.

"If I wasn’t an actor, I would definitely do things to my hair. I would cut it more, I would dye it more. At some point I want to do a total boy cut, completely—not a pretty, girly version—like a straight up James Dean haircut," she told the site.

Okay, that's a little out there -- but not too crazy. But here's the real bombshell:

"And then, I’m definitely going to shave my head before I die. I will definitely tattoo my head while it’s shaved before my hair grows back," Stewart shockingly revealed. "I’m not sure which part, probably the bottom quadrant in the back. I don’t know what the tattoo would be, yet," she admitted. "Still thinking."

Whoa. Despite the fact that the actress already has several tattoos (which she is keeping private) -- that's a pretty serious decision. Would she get something to commemorate her relationship with Robert Pattinson? Or maybe some ink of her new dog? How about a 'Twilight' tattoo?
